Why is this unpinned????

I'd learn a little about the Queen's Gambit, and for giggles, I would take up the King's Indian Attack - fun opening, with some neat tactical ideas and throws a lot of people off their game plan.

King's Gambit can be lots of fun too, though it is not as strong as it once was - there are some nice defenses to it, though I still get a lot of wins with it.

You're mistaken. It was never really pinned in the first place.
